WILLIAM DULLES, OF NEW YORK, N. Y.

MACHINE FOR ROLLING SHEET GLASS.

To all whom it may concern:

Be it known that I, WILLIAM DULLEs, a citizen of the United States, residing at New York city, New York, have invented a certain new and useful Improvement in Machines for Rolling Sheet-Glass, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is an elevation of one end of my glass rolling table. Fig. 2 is a side elevation of the same. Fig. 3 is a top plan view of the same. Fig. 4 is an end elevation view of the opposite end of said table. Fig. 5 is a side elevation of the same. Fig. 6 is a top plan view of the same, and Fig. 7 is a detail view of a modified form of trang.

This invention relates to a new and useful improvement in machines for rolling sheet glass and particularly to that part of the machine known as the trangs.

My invention consists in means for shifting or moving the trangs so as to position a trang of the proper thickness, depending upon the distance the roller is to be located above the table.

Another object is to provide means whereby the trang may be automatically shifted so that the roller will roll thin and thick glass alternately, said means being operable by the roller when it approaches or reaches the end of the table.

My invention is particularly useful in rolling wire glass wherein a single thickness of glass is first rolled, then wire mesh arranged thereon, and by the reversed movement of the roller a second layer or thickness spread over the first thickness. This is commonly known as the sandwich method. According to my present invention, in connection with the manufacture of wire glass, the roller will roll the first thin layer of glass and as it approaches the end of the table, after rolling said first layer, the trang shifting means will be operated either by hand, if desired, or preferably automatically by the weight of the roller, so as to shift the trang or move another trang in position so that when the roller again traverses the table to roll the second layer or thickness of glass, said roller riding upon a thicker trang, will be located at such distance above the table as to properly spread Specification of Letters Patent.

the second or finishing layer of glass over the first layer and the interposed wire mesh. As the roller approaches the end of the table from which it started, it is preferably made to automatically shift the trangs so as to bring the thinner trang into cooperative relation with the roller for the rolling of the first thin layer of glass of the next sheet.

Roller-supporting plates having inclined ends are arranged upon the ends of the table so as to elevate the roller above the thick trang or permit its descent to the thin trang without shock or jar. While I have shown two difierent posit-ions of the trang, it is obvious that a trang of three thick nesses could be used to arrange the roller at three different positions above the table. That is, for instance, where a thinner finishing layer of glass is spread upon the completed sheet.

In the drawings, 1 indicates the table and 2 the roller.

3 is the trang which is composed of a thin part 3 and a thick part 3*. There is a trang located at each side of the table but as the mechanism cooperating with the same is identical I will describe but one trang. Trang 3 is connected by means of rock arms 4 to a rock shaft 5 mounted in suitable bearings 6 arranged on the side edges of the table. On one end of rock shaft 5 is a rock arm 7 connected by a twisted link 8 to a lever 9 whose opposite end is pivoted at 10 to an elevating frame 11. This frame 11 is connected to the table in any suitable manner and to its companion by means of tie bolts. The inneredges of the frame are provided with inclines 11 whereby as the roller leaves the thin trang 3 it will be elevated above the thick trang 3 the continued onward movement of the roller depressing the lever 9 and through the mechanism described moving the trang inwardly so as to bring the thick trang 3 in the path of the roller for cooperative relation therewith. When the roller again traverses the table, it will ride upon the thick trang 3 Assuming that in the first movement the roller riding upon the thin trang 3 has spread a thin layer of glass upon the table, it is manifest that if wire mesh is arranged upon said thin layer and another pour of glass dumped in front of the roller, that its return movement, upon the thick tran'g 3 will spread the second pour into the form of a layer over the wire mesh, thus forming a complete sheet of wire glass by the socalled sandwich method. As the roller approaches the end of the table whenceit started, it will ride uponits supporting frame 11 similar to the manner just described to cooperate with alever 9 t-o which is connected a link 8 in all respects like the corresponding parts" before described. At this end of the table, however, as shown Figs. 4:, 5 and 6, link 8, instead of being connected to a rock arm 7 rigidlysecured to; the rock shaft5, is 'connected to a lever 13 pivoted? at13 to theend of the table and connected at its upper end 'to a rockarm 14 fiXedto the shaft 5." By this construction the weight off the roller upon the"lev'er 9 will operate through the parts just de-- scribed to move the trang outwardly soas tobring-the thin portion 3 'thereofin co-: operative relation with the roller'2. Hence when another pour; of glass is dumped in frontiof'the roller the roller riding upon the thinftrang will'sprad a thin layerupon the-table inrea1di ness'-for the wire 'meshin the secondlayer, as heretofore described. *In Fig. 7 Iha-veshown a trang'15of the formof a rectangu'lanbarwhich may or'may be-laidflat "for the first layer of glass,as' shownat the left of said figure and beset on edge for thesecond layeras shown'at the right ofsaid figure. The bar may be mounted to rotate in suitable bearings at its ends and to be operated by rack and pinion mechanism from the rock shaft 5 ina manner Which'is well known.
